The Process Engine Web Service is a standards-based Web services implementation. It is deployed as a Web application on the supported application server.
Additionally, the following SOAP version is supported:
The Process Engine Web Service uses the framework that is provided by IBM® Axis2. For version information, see the IBM FileNet® P8 system requirements web page. Axis2 is a Web services platform that provides development tools, a runtime server, and management services. Axis2 runtime services isolate common services from business applications. The runtime server processes SOAP messages and provides a runtime container for web services. The SOAP message processor converts SOAP messages into application invocations, mapping XML types to Java™ types. The runtime service container hosts and manages the deployed applications.
The Web service operations are stateless. The caller is required to pass in user criteria as part of the SOAP WS-Security header for the operation. For more information, see Creating the WS-Security Header.
The Process Engine Web Service (ProcessEngineWS) provides a subset of the Process Java API, and (per WS-I Basic Profile 1.0) uses document/literal SOAP messaging. The reference documentation for the Process Engine Web Service links each operation to the associated Process Java API class and method.
The Process Engine Web Service must access a Content Platform Engine connection point to create and maintain a session. The default connection point for the Process Engine Web Service is PEWSConnectionPoint. See Using Multiple Regions for instructions in specifying a connection point in the SOAP header.
